The top Republican on the Senate judiciary committee, Lindsey Graham, said that as soon as the party takes control of the chamber next year, they’ll get to work on sending Donald Trump legislation to implement hardline immigration policies.

“In January of 2025, the Republican Senate will make its top priority a transformational border security bill that will be taken up and passed by the budget committee, increasing the number of bed spaces available to detain people instead of releasing them, increasing the number of Ice agents to deal with people who should be deported, finish the wall and put … technology on the border, so we’ll have operational control of the border. That’s going to be our top priority,” said Graham.

Trump and the Republicans have plenty of other priorities once they take power in Washington, but Graham said that border security was what they would address first.

“I want to cut taxes. We will cut taxes. But as to the Senate, transformational border security goes first through reconciliation,” Graham said, referring to the parliamentary procedure that will allow Republicans to circumvent a filibuster by Democrats in the Senate.

Graham vowed:

We’re going to start sending people out of the country that present a threat to us and should never been here to begin with.

Democratic Senate judiciary committee chair Dick Durbin kicked off the hearing into Donald Trump’s plan for mass deportations by warning that such an effort would inhumane, prohibitively expensive and harmful to the US military.

Trump and his advisers have proposed using active-duty troops to deport every undocumented person in the country. In his opening statement, Durbin warned that doing so could harm the military’s readiness.

“Things change when you go from high flying campaign rhetoric to ground … Think about for a moment, using our military for a mass deportation plan. I’m sure it would have a damaging impact on the morale of the troops, rounding up people in their own communities at a time when we’re already facing the most serious recruitment challenge in years,” Durbin said.

“In addition to weakening our military, it would cost hundreds of billions of dollars to deport every undocumented immigrant our country. It would damage our economy and separate American families. Instead, we should focus on deporting those who are truly a danger to America, and we should give the rest a chance to earn legal status. They would have to register with the government, certainly pay their taxes and submit to serious background checks.”

The Senate judiciary committee has just started its hearing focused on Donald Trump’s mass deportation plans, and the harms it could do to communities across the country.

With Donald Trump vowing to implement hardline immigration policies including mass deportations as soon as he takes office, a group of Democratic senators is asking Joe Biden to approve new policies they say would allow some migrants to remain in the country.

“Mass deportations would jeopardize the safety and security of millions of mixed-status families, sow deep distrust and fear in the communities we represent, and destabilize the U.S. economy,” seven senators representing Illinois, New Jersey, Nevada, New Mexico, Hawaii and California said today in a letter to Biden.

“We write now because the window to secure and finalize your administration’s policies is closing rapidly. We urge you to act decisively between now and the inauguration of the president-elect to complete the important work of the past four years and protect immigrant families.”

Among the steps the group proposes is expanding a program that shields from deportation citizens of certain countries that are determined to he unsafe. They also call to expedite processing of applicants for Deferred Action for Childhood Arrivals, which shields from deportation undocumented people brought into the US as children.

Democrats are likely to reiterate their call to the outgoing president at the Senate judiciary committee hearing on Trump’s mass deportation plan that is scheduled to start at 10am. You can read the full letter here.

Good morning, US politics blog readers. Donald Trump was having a certain kind of night last night – the sort of night where one mistakes Canada for a state, and prime minister Justin Trudeau for its governor. “It was a pleasure to have dinner the other night with Governor Justin Trudeau of the Great State of Canada. I look forward to seeing the Governor again soon so that we may continue our in depth talks on Tariffs and Trade, the results of which will be truly spectacular for all!” Trump said on Truth Social. Just 41 days remain until he can write this sort of thing from the White House.

Meanwhile, Democrats are using their final days in control of the Senate to shine a spotlight on the harms Trump’s vows of mass deportations would do to American communities. At 10am, the judiciary committee will convene a hearing on how the president-elect’s signature campaign promises will “separate American families, harm our armed forces and devastate our economy”. The Democrats have summoned a retired major general and an undocumented Philadelphia prosecutor who is temporarily shielded from deportation to testify. The GOP has called the mother of a Maryland woman who was raped and murdered, allegedly by an undocumented man.

Here’s what else is going on today:

• More than 75 Nobel laureates have reportedly signed a letter asking senators not to confirm conspiracy theorist Robert F Kennedy Jr as secretary of the health and human services department, after Trump nominated him last month.

• Joe Biden will defend his economic record in a speech from the Brookings Institution in Washington DC at 12.15pm.

• Karine Jean-Pierre, the White House press secretary, takes questions from reporters at 2pm.
